They are responding specifically to the "AI should automatically report" suggestion. An AI model on its own (without a service built up around it) would not have any mechanisms to use the network, reach out to an FBI hotline, or do anything like this. Protections / limits would have to be added by the operator somehow (or the distributor of models themselves).
A model by itself though… you might as well ask a pencil to report someone for drawing graffiti. It does not make sense.
